Description
Technical Field
[0001] The utility model relates to the technical field of cameras, and more specifically, to a power line carrier communication network camera. Background Art
[0002] The power line carrier communication network camera is a device that uses power line communication technology to transmit data and images through power lines. It is widely used in places that require security and can remotely monitor and control the image.
[0003] The cameras currently on the market are usually composed of a mounting base, a mounting frame and a camera body. During installation, the mounting base is installed in a pre-set position to achieve the function of positioning and installing the camera. In the prior art, in order to improve the monitoring range and increase the practical effect of the power line carrier communication camera, it is necessary to set a slide rail in the application environment, and slide the mounting base of the power line carrier communication camera on the slide rail. Then, the mounting base can be driven to move by a mobile driving device (for example, a walking vehicle is set on the mounting base, or a mobile driving device such as a linear motor is directly used). Driven, thereby driving the power line carrier communication camera to move within a certain range, so that the position of the power line carrier communication camera can be controlled in real time as needed.
[0004] However, in actual use, when the camera needs to capture images quickly, the mounting base will drive the camera installed on the top of the mounting frame to move quickly. The movement of the mounting base is usually driven by a mobile drive device. In scenarios that require fast movement, the overall speed of the power line carrier communication camera and the mounting base is relatively high during the movement. When the mobile base stops, the power line carrier communication camera cannot stop immediately due to inertia, so it shakes after the mounting base stops, which will cause the monitoring screen to shake and affect the monitoring effect. The greater the speed, the greater the shaking of the power line carrier communication camera when it stops, which is also likely to cause damage to the mounting frame and reduce the service life of the equipment. Utility Model Content
[0005] The utility model provides a power line carrier communication network camera, and aims to solve the following problem: in a scene where the existing mounting base needs to move quickly, the overall speed of the power line carrier communication camera and the mounting base is relatively high during the movement. When the moving base stops, the power line carrier communication camera cannot stop immediately due to inertia, so that it shakes after the mounting base stops, which causes the monitoring screen to vibrate and affects the monitoring effect. Moreover, the greater the speed, the greater the shaking of the power line carrier communication camera when it stops, which is also likely to cause damage to the mounting frame and reduce the service life of the equipment.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a power line carrier communication network camera, comprising a camera body, a mounting frame, a linear drive guide rail structure and a mounting seat; the camera body is connected to the mounting seat through the mounting frame, the mounting seat is slidably arranged on the linear drive guide rail structure, a connecting seat is arranged between the mounting frame and the mounting seat, the connecting seat is fixedly connected to the mounting frame, and the connecting seat is slidably arranged on the mounting seat;
[0007] Buffer assemblies are provided at both ends of the connecting seat, and the buffer assemblies include a piston box and a piston. The piston box is fixedly installed on the mounting seat, the piston is fixedly connected to the end of the connecting seat, and the piston is slidably arranged inside the piston box; the sliding direction of the connecting seat on the mounting seat is arranged in the same direction as the movement direction of the mounting seat, which is conducive to alleviating the inertia generated by the camera body after rapid movement, causing the camera body to vibrate the monitoring screen.
[0008] In a preferred embodiment, the buffer assembly also includes a pressure relief structure, which is arranged on a side of the piston box away from the connecting seat, and the piston box is connected to the external air through the pressure relief structure; the pressure relief structure is an elastic structure such as a rubber sheet structure, and the pressure relief structure is embedded and installed in the side wall of the piston box. Tiny pores are arranged in the pressure relief structure, and the pores of the pressure relief structure are in a closed state when the pressure inside and outside the piston box is consistent. When the pressure difference between the inside and outside of the piston box reaches a certain value, the air pressure squeezes the pressure relief structure to open the pores. However, when the pressure difference between the inside and outside of the piston box is opened, the air flow speed of the pores is limited, and the buffering pressure on the piston in the piston box can still be maintained, which is conducive to convenient exhaust when the air pressure in the piston box is too high.
[0009] In a preferred embodiment, a reamer is movably provided inside the piston box, and the reamer is correspondingly arranged on one side of the pressure relief structure. A connecting plate is fixedly connected to the back end of the reamer, and a telescopic rod is connected to the surface of the connecting plate, and the outer end of the telescopic rod is connected to the inner wall of the piston box on one side close to the pressure relief structure; the reamer is composed of a triangular piece and a cross bar that intersect vertically, and the triangular piece is fixedly connected to the surface of the cross bar, and the tip of the triangular piece is arranged toward the pressure relief structure, which is conducive to expanding the size of the pressure relief structure during the contact between the reamer and the pressure relief structure, so that the air inside the piston box can be quickly discharged when the pressure is too high.
[0010] In a preferred embodiment, a protective cover is provided on the top of the camera body, an air pipe is provided on the top of the camera body, a plurality of nozzles are provided on the surface of the air pipe, the air pipe is provided on the top of the camera body and is connected to the protective cover; an air guide box is provided on the outside of the piston box, the pressure relief structure is connected to the air guide box, the air guide box is fixedly provided on the surface of the piston box, an air guide pipe is connected through the surface of the air guide box, the air guide box is connected to the air pipe through the air guide pipe, and the gas discharged from the inside of the piston box is used to facilitate the cleaning of dust on the surface of the camera body, thereby improving the practicality of the camera body.
[0011] In a preferred embodiment, the outer wall of the piston box is fixedly provided with an anti-collision block, which is arranged on one side of the piston box close to the end of the mounting seat. The anti-collision block is arranged in a circular pad shape, and the anti-collision block is used to reduce the vibration of the mounting seat and the inner wall of the linear drive guide structure after collision.
[0012] Technical effects and advantages of the utility model:
[0013] The utility model provides a buffer component. When the camera body continues to move in the sliding direction due to inertia, the end of the connecting seat drives the piston to slide in the direction of the pressure relief structure inside the piston box. When the piston slides in the direction of the pressure relief structure, the piston compresses the air inside the piston box, and the air pressure provides a buffer, so that the camera body can stop slowly and reduce inertial vibration.
[0014] The utility model provides a reamer. When the piston moves to a certain distance through the pressure relief structure and the air pressure inside the piston box exceeds a certain value, the pressure relief structure will start to exhaust air outwards. When the piston moves to contact the surface of the connecting plate, the reamer is squeezed in the direction of the pressure relief structure by the piston squeezing the connecting plate. During the movement of the reamer, the reamer contacts the pressure relief structure to expand the pressure relief structure, so that the air inside the piston box can be quickly discharged to achieve rapid pressure relief. The piston loses the thrust generated by the excessive air pressure and stops slowly due to the loss of force, so that the connecting seat can stop slowly. The practicality of the device can be improved in conjunction with the buffer component. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example
[0023] Refer to the instruction manual Figure 1-Figure 6 A power line carrier communication network camera, including a power line carrier communication network camera, including a camera body 1, a mounting frame 2, a linear drive guide structure 3 and a mounting seat 5. The camera body 1 is connected to the mounting seat 5 through the mounting frame 2, and the mounting seat 5 is slidably arranged on the linear drive guide structure 3. A connecting seat 4 is arranged between the mounting frame 2 and the mounting seat 5, and the connecting seat 4 is fixedly connected to the mounting frame 2, and the connecting seat 4 is slidably arranged on the mounting seat 5;
[0024] A buffer assembly is provided at both ends of the connecting seat 4, and the buffer assembly includes a piston box 7 and a piston 12. The piston box 7 is fixedly mounted on the mounting seat 5, and the piston 12 is fixedly connected to the end of the connecting seat 4, and the piston 12 is slidably arranged inside the piston box 7; the sliding direction of the connecting seat 4 on the mounting seat 5 is arranged in the same direction as the movement direction of the mounting seat 5, and the buffer assembly also includes a pressure relief structure 8, which is arranged on the side of the piston box 7 away from the connecting seat 4, and the piston box 7 is connected to the external air through the pressure relief structure 8; the pressure relief structure 8 is an elastic structure such as a rubber sheet structure, and the pressure relief structure 8 is embedded and installed in the side wall of the piston box 7, and tiny pores are arranged in the pressure relief structure 8. When the pressure inside and outside the piston box 7 is consistent, the pores of the pressure relief structure 8 are in a closed state, and when the pressure difference between the inside and outside of the piston box 7 is generated and reaches a certain value, the air pressure squeezes the pressure relief structure 8 to open the pores, but when opened, the air flow speed of the pores is limited, and the buffering pressure on the piston 12 in the piston box 7 can still be maintained.
[0025] It should be noted that the camera body 1 is a video surveillance device developed using power line carrier communication technology to achieve video transmission on power lines. When it is necessary to quickly capture the movement of the picture, a piston structure can be formed using the piston 12 and the piston box 7. Specifically, a sealing ring is arranged between the piston 12 and the piston box 7. When the mounting seat 5 stops, the camera body 1 together with the connecting seat 4 can continue to move due to inertia. At this time, the piston 12 can be driven to compress the air in the piston box 7 to provide a buffer with the air pressure, so that the camera body 1 stops slowly and reduces inertial vibration. However, if the air compression in the piston box 7 is large, it will also cause a rebound on the piston 12. When the pressure in the piston box 7 exceeds a certain value, the pressure relief structure 8 starts to exhaust outwards, and the exhaust speed of the pressure relief structure 8 is less than the compression speed of the air by the piston 12 when it moves in the piston box 7, thereby ensuring that a certain air pressure can be maintained in the piston box 7 to provide a buffering force for the piston 12.
[0026] Furthermore, a reamer 15 is movably provided inside the piston box 7, and the reamer 15 is correspondingly arranged on one side of the pressure relief structure 8. The reamer 15 is composed of a triangular piece and a cross bar that intersect vertically; the triangular piece is fixedly connected to the surface of the cross bar, and the tip of the triangular piece is arranged toward the pressure relief structure 8. The back end of the reamer 15 is fixedly connected to a connecting plate 14, and a telescopic rod 13 is connected to the surface of the connecting plate 14. The outer end of the telescopic rod 13 is connected to the inner wall of the piston box 7 on one side close to the pressure relief structure 8.
[0027] In the above embodiment, when the piston 12 moves to a certain distance through the pressure relief structure 8, when the air pressure inside the piston box 7 exceeds a certain value, the pressure relief structure 8 will start to exhaust air outwards, and when the piston 12 moves to contact the surface of the connecting plate 14, the connecting plate 14 is squeezed by the piston 12, and the reamer 15 is squeezed in the direction of the pressure relief structure 8, and in the process of the reamer 15 moving, it contacts the pressure relief structure 8 to expand the pressure relief structure 8, so that the air inside the piston box 7 can be quickly discharged to achieve rapid pressure relief. The piston 12 loses the thrust generated by the excessive air pressure and stops slowly due to the loss of force, so that the connecting seat 4 can stop slowly, and the practicality of the device can be improved in conjunction with the buffer component.
[0028] Furthermore, a protective cover is provided on the top of the camera body 1, an air pipe 16 is provided on the top of the camera body 1, a plurality of nozzles 17 are provided on the surface of the air pipe 16, the air pipe 16 is provided on the top of the camera body 1 and is connected to the protective cover; an air guide box 9 is provided on the outside of the piston box 7, the pressure relief structure 8 is connected to the air guide box 9, the air guide box 9 is fixedly provided on the surface of the piston box 7, an air guide pipe 10 is penetrated and connected to the surface of the air guide box 9, the air guide box 9 is connected to the air pipe 16 through the air guide pipe 10, after the air inside the piston box 7 is discharged into the air guide box 9 through the pressure relief structure 8, it can then be introduced into the air guide pipe 10 through the air guide box 9 and discharged from the nozzle 17, and at the same time, the surface of the camera body 1 contacts the air discharged from the nozzle 17, so that it can cooperate with the dust cleaning process on the surface of the camera body 1, and the practicability of the device can be improved.
[0029] Furthermore, the outer wall of the piston box 7 is fixedly provided with an anti-collision block 11, which is arranged on one side of the piston box 7 close to the end of the mounting seat 5. The anti-collision block 11 is arranged in a circular pad shape. The anti-collision block 11 can reduce the vibration of the mounting seat 5 and the inner wall of the linear drive guide structure 3 after the collision.
[0030] In this embodiment, the implementation scenario is specifically as follows: when the camera body 1 needs to capture images quickly, the linear drive guide structure 3 is used to drive the mounting seat 5 to drive the camera body 1 set on the top of the mounting frame 2 to move quickly. Since the overall speed of the camera body 1 and the mounting seat 5 is relatively high, after the mounting seat 5 stops suddenly, the camera body 1 continues to move in the sliding direction due to inertia, and at the same time, the end of the connecting seat 4 drives the piston 12 to slide in the direction of the pressure relief structure 8 inside the piston box 7. While the piston 12 slides in the direction of the pressure relief structure 8, the piston 12 can be used to compress the air inside the piston box 7, and the air pressure provides a buffer, so that the camera body 1 can stop slowly and reduce inertial vibration;
[0031] When the piston 12 moves to a certain distance through the pressure relief structure 8 and the air pressure inside the piston box 7 exceeds a certain value, the pressure relief structure 8 will start to exhaust air outwards, and when the piston 12 moves to contact the surface of the connecting plate 14, because the piston 12 compresses the piston box 7 and the internal air pressure value is too high at this time, rebound will occur, the piston 12 squeezes the connecting plate 14 and also squeezes the reamer 15 in the direction of the pressure relief structure 8, and in the process of the reamer 15 moving, it contacts the pressure relief structure 8 to expand the pressure relief structure 8, so that the air inside the piston box 7 can be quickly discharged to achieve rapid pressure relief, the piston 12 loses the thrust generated by the excessive air pressure and stops slowly due to the loss of force, so that the connecting seat 4 stops slowly, and at the same time, the air inside the piston box 7 is discharged into the air guide box 9 along with the discharge of the pressure relief structure 8, so that the air can be introduced into the air guide pipe 10 through the air guide box 9 and discharged from the nozzle 17, and at the same time, the surface of the camera body 1 contacts the air discharged from the nozzle 17, so that it can cooperate with the cleaning of the surface of the camera body 1, thereby improving the practicality of the device.
[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
